title: Valsalva leak point pressure and bladder volume.
abstract: Twenty-nine females with stress urinary incontinence (SUI) were evaluated with fluorourodynamics, including Valsalva leak point pressure (VLLP) determinations. VLPP was determined at bladder volumes of 150 ml, 300 ml, and total bladder capacity. The VLPP determinations were analyzed using the signed rank and sign tests. Fluoroscopy was used to analyze change in type of SUI based on bladder volume. No significant difference in VLPP determinations was noted at various bladder volumes. No change in type of SUI was noted at various bladder volumes. We believe the volume in the bladder does not alter the category of SUI or statistically change the VLPP determination.
